My coworker has a permanent ad for free gas in the upper left window of Internet Explorer. It says Click here to claim your FREE* year of gas!!. Once clicked, it goes to a page on everyfreegift.com. I'm not Mac user, but I'll try to provide the proper details: OSX 10.3.9 with Internet Explorer 5.2.3. IE isn't the main browser--she uses Safari most of the time. Here is a screenshot. Has anyone seen something like this? Where are Browser Helper Objects (BHO) for IE located in OSX? I haven't found anything on the internet about this.
